CCDLING TOWERS 

THE functions of water cooling plants need 
not be enlarged upon; they arc well known. 
Wherever water is deficient in quantity 
and even in quality, they form a necessary 
adjunct to modern power plants in connection with 
steam oi .-movers, air-com- 

pressors. . ; the like. 

CcK)ling Towers are sometimes looked upon 
as necessary evils; itisneverthelessof importance to 
give to thisend of the power plant as much attention 
as to boilers and t ^ • so that the whole may 
blend intoahomo^ ut returning the highest

concrete or brick, but on the whole, the very con- 
siderably increased first cost is not justified by the 
longer life obtained. The tower itself is of rect- 
angular or polygonal shape and should, of course, 
be of ample size (this is often sinned against) to 
pass the mixture of air and vapour resulting from 
efficient cooling. We have paid special attention 
to an efficient and accurate water distribution 
which is effected by venturi nozzles and splash 
plates ; these being made of glazed porcelain are 
practically indestructible. The cooling bars or 
hurdles are of remarkable strength, and are rigidly 
held in position and supported without the use of 
nails. They cannot warp or sag, and at the same 
time the design is such that a most intmiate mix- 
ture of air and water is obtained with a maximum 
cooling surface and a minimum resistance. Special 
precautions are taken by suitably arranged wind 
screens and partitions to ensure that all parts of the 
cooling stack receive an ample and equal supply of 
air from the atmosphere. In short, our design com- 
bines the qualities required of an up-to-date cooling 
tower, and represents : 

Strength with low capital cost; 
Efficiency and reliability. 

Where space is valuable, or altogether insuffi- 
cient for the duty required, we recommend the 



'^VISCC SUPER COOLING TOWER 

which occupies Httlc more than half the space of a 
standard cooler, and is particularly suitable for large 
units. The design is unique, and the efficiency far 
ahead of any other construction in wood. Although 
more expensive than the standard cooler, if the cost

is largely used ; an example oi which is represented 
by illustration No. 54. To all intents and pur- 
poses, these open type coolers consist of the interior 
of a chimney cooler without the chimney itself, rely- 
ing largely on riie natural air currents to produce 
the requisite mixture of air and water. Air is never 
still, and even a comparatively slight movement 
will pass the volume of air required to obtain the 
desired cooling effect. In most cases, the structure 
IS surrounded b\ Iou\ res to pi event undue splash- 
ing of spray upon the surrounding property at high 
winds.
